SPRING-BALANCE SCALE.

SPECIFICATION forming part of Letters Patent No. 366.491, dated July 12,1887.

Application filed November 23, 1886. Serial No. 219,657. (No modal-l Toall whom it may concern;

Be it known that I, OHARLEs R. MAGUIRE, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Spring-Balance Scales, of which thefollowing is a specification.

This invention relates to the improvement in the case-fronts ofspring-balances, and is illustrated in the accompanying drawings, inwhich- Figure l is' a front view of a spring-scale embodying myimprovement. Fig. 2is aside view of same. Fig. 3 is a view of the sidesupporting arm. Fig. 4 is a View of the detachable front plate, showingthe same in one piece. Fig. 5 is aview ofthe front plate, showing itmadein four pieces.

The object of this invention is to provide an ornamental front plate toentirely surround the dial-case of spring-balance scales. These frontplates may be made of any suitable material, and are to be plated orotherwise ornamented, and are so constructed and applied to thescale-cases that they may be attached to an old scale as well as a newone, and when, by use or wear of the scale, the plates become marred ordisfigured, they may be removed for replating or reornamentation withoutin the meantime disabling the scale-that is, with out unfitting thescale for use while the said plates are off.

The usual scale parts need not be described.

The dial-case A and the two flanges I) of the spring-case I) are ofordinary construction. The improved detachable front plate is annularorring-shaped, and entirely surrounds the dial-case A. This plate hastwo i rregularshaped parts, 0 G,Which are diametrically opposite eachother, and two plain semicircular parts, (I, which connect with the saidtwo irregular-shaped parts. The four parts comprise the annular plate,having a round central opening, a, for the dial-case, around which itfits. The plate has holes f for the entrance of screws f ,whereby it isattached to thetwo flanges b of the case.

i To render the attachment secure and dlll21 this arm has a hole, 2'.Ascrew, 72, through the k semicircular part d enters the said hole, andthereby stays the said part.

This ornamental front plate may be made in one piece, as shown in Fig.4, or in four pieces, as shown in Fig. 5, to be united. This kind of aplate may be used on scales having a single dial or a double dial.

In some instances ascale may have an ornamental detachable front plate,as described, With but one irregularly-shaped part.

I am aware that it is not new to provide a spring-balance scale with aremovable segmental front plate, such being shown in a former patentgranted to me, and bearing Serial No. 338,535, and of date March 23,1886; but in the invention herein is shown a front plate of a differentconstruction, and secured in amanner that the same may be readilydetached from the device without a separation of the Working parts andindicating parts.

Having described my invention, I claim and desire to secure by LettersPatent of the United States- In a spring-balance scale, the combinationof the dial-case, having flanges b b, with a detachable front platehaving parts 0 O, semicircular side parts, at d, and opening 6, asshown, the bars 9, and the side supporting arms, h, having openings 2',the said front plate being secured to the said flanges b, allsubstantially as described.

In testimony whereof Iaffix my signaturein the presence of twowitnesses.

CHARLES R. MAGUIRE.
